[Analysis of fever in 58 cases of infective endocarditis]. / Análise da febre em 58 casos de endocardite infecciosa.

PURPOSE: To evaluate if fever is an objective criterion in the assessment of response to antibiotic therapy and in the prognosis of patients undergoing treatment for infective endocarditis (IE). METHODS: Fifty-eight cases of IE, occurring from January 1980 to December 1989 have been analysed retrospectively in this study. Emphasis was given to the clinical history and body temperature changes during the first five weeks of treatment. Patients were divided in three groups according to the number of febrile peaks per week. Temperature was assessed weekly from each patient's highest peak weighed average. RESULTS: At the first exam, 52 patients (86.2%) presented fever. All patients had at least one episode of fever during their hospitalization. There seemed to be a relation between the number of febrile peaks during a one week period and the mean body temperature, so that these patients who presented four or more peaks in a week had a higher mean body temperature than those with two or less febrile peaks during the week. After the second week of treatment, patients with two or less febrile peaks had a 93.1% survival and average of 35.5 days of hospitalization, whereas those with three or more febrile peaks had 63.6% survival and an average of 47.5 days of hospitalization. CONCLUSION: The results of this study show that the intensity of fever is linked to the number of febrile peaks per week, regardless to treatment duration. Should there be three or more febrile peaks weekly after the second week of treatment, therapeutic strategy should be reviewed, considering even surgical treatment. In many cases, the persistence of fever represented the clinical expression of complications which determined a higher mortality rate and a longer hospitalization.

[Cor triatriatum]. / Cor triatriatum.

A 16-year-old patient was evaluated for congestive heart failure and pulmonary hypertension, suggesting mitral valve stenosis. A left atrial membrane with a 4 mm orifice was seen in echocardiography and angiography, and a diagnosis of cor triatriatum was made. The membrane was successfully removed by surgery.
